[SOLVED] MQTT state does not change in Home Assistant from FHEM

[frank.j@me.com]

Hi all,

I have successfully set up a mosquito MQTT server, and I can control a light in FHEM via the Home assistant. When I change the state in HA, the state in FHEM changes correctly, and the light switches on and off.

When I switch the light on via a FTM55 switch or in FHEM direct however, the icon in HA does not change (the light is not indicated to be on in the HA dashboard.

So apparently HA does not see the state correctly, what am I doing wrong?

configuration.yaml in HA:

Code Auswählen Erweitern

light:
  - platform: mqtt
    schema: template
    name: "Vogels"
    command_topic: "enocean/FSR14_1_2/set"
    state_topic: "enocean/FSR14_1_2/state"
    command_on_template: "on"
    command_off_template: "off"


Code in FHEM:

Code Auswählen Erweitern

define FSR14_1_2 EnOcean FF95270E
setuuid FSR14_1_2 5e2d7ee7-f33f-8300-12f3-8b29df4a7cf33adc

attr FSR14_1_2 room BGG,Homekit
attr FSR14_1_2 subDef FFB87A06
attr FSR14_1_2 subType gateway


This is the message as received by the MQTT server:

Code Auswählen Erweitern

Imo FHEM/MQTT_GENERIC_BRIDGE is doing what it is expected to do according to the message you have shown: Send out the state to the configured topic when switched.

So this seems more liekly to be more a Problem on the HomeAssistant side. Perhaps the "payload_on" etc. is missing as mentionned in https://forum.fhem.de/index.php/topic,115279.msg1147334.html#msg1147334

I managed to fix it with help from above:

The HomeAssistant code needs a state template in my case:

Code Auswählen Erweitern

  - platform: mqtt
    schema: template
    name: "Wastafel"
    command_topic: "enocean/1_b1/set"
    state_topic: "enocean/1_b1/state"
    command_on_template: "on"
    command_off_template: "off"
    state_template: "{% if value == 'on' %}on {% else %} off {% endif %}"
